Three times Jose Valverde would lead the league in Saves and did so for three different teams. Valverde proved to be an effective closer for many years and he did come close to 300 Saves, however his overall stats do not put him in the Hall of Fame range and his very poor playoff performances could keep him off of the ballot.
While Jason Giambi is better known for being an inflated PED user, the fact remains that he was a very good hitter who was a former American League MVP. Giambi would go to five consecutive All-Star Games, blasted 440 Home Runs with a .516 career Slugging Percentage over a twenty-year career. He would also show solid plate discipline with three On Base Percentage Titles and retired with a very good 50.4 bWAR.
There is a good chance that Jason Bartlett will not make the ballot, as he is well under 1,000 Hits for his career. Still, he is a former one time All Star who had decent defensive skills, which brought him to a 18.4 bWAR.
